This article deals with the features of the evaluation of changes in the functional state during the professional activity of operators. We estimated the dynamics of the functional state and efficiency of operators under the effect of aircraft noise and individual psychophysiological characteristics. We also investigated changes in the functional state of operators depending on their psychological characteristics. It was found that changes in the functional state of the organism in operators with high levels of anxiety, low degrees of extraversion, and high emotional lability were more pronounced in the modeling of operator activity with exposure to aircraft noise, as evidenced by significant changes in psychophysiological parameters. After 60 minutes of noise stress, the latent period of a simple and a complex sensorimotor reaction in introverts increased by 9.1% (p < 0.05) and 8.1% (p < 0.05), respectively. In the group of subjects with high levels of anxiety, there was a decrease in the general state, activity, and mood by 18.9% (p < 0.01), 20.9%, and 14.9% (p < 0.05), respectively, and a decrease in the accuracy of reaction to a moving object by three times (p < 0.05). The latent period of simple sensorimotor reaction in emotionally labile subjects after the exercise was increased by 15% (p < 0.05), and the reaction time on a moving object was increased by 8.9% (p < 0.05) as compared with the group of emotionally stable subjects. Thus, the data suggest that changes in the functional state of operators depends on the level of extraversion, personal anxiety, and emotional lability, and does not depend on the level of behavioral regulation, which must be taken into consideration during the assessment of functional state. © 2017, Pleiades Publishing, Inc.

This article is focused on the development of the structure and content of consolidating orientation of pedagogical functions of university teachers in international students’ training. The leading method of research is the modeling method that allows producing of the established structure’s and content’s justification of consolidating orientation of teachers’ pedagogical functions. The article deals with the structure and content of the concept “consolidating orientation of university teachers’ pedagogical functions”; defines the content of educational process’s updating in international students’ training through the implementation of the consolidating orientation of teachers’ pedagogical functions; substantiates the educational-methodical complex of educational process’s updating of international students on the basis of the results of the study. The productivity of educational-methodical complex is proved using the criteria of formation of: cross-cultural interaction competence; ability to overcome barriers of cross-cultural communication; skills of objective evaluation of their own positions in the cross-cultural interaction with teachers, fellow students, in society; ability to plan cross-cultural interaction with others in the course of their professional activities; planning abilities of “settling” in the region, and others. © 2016 Fedorenko and Bykova.

Ten evolutionary conservative sequences with high identity level to homological sequences in other mammal species were revealed in 5'-flanking region of casein's genes cluster. Five novel SNPs located inside of the evolutionary conservative regions were identified. The binding sites were revealed to be present in one allelic variant of four detected SNPs. So these SNPs were considered as rSNPs. Significant differences of allelic frequencies were revealed between beef cow's group and dairy cow's group in two rSNPs (NCE4, NCE7, p < 0.001). Different alleles of those two rSNPs were shown to be associated with some milk performance traits in Black-and-White Holstein dairy cows. Significant difference of protein percentage has been found between cows with G/G and A/A genotypes (P < 0.05) and A/G and A/A genotypes (P < 0.05) for NCE4 polymorphism. The groups of animals with genotypes G/G and A/G for NCE7 polymorphism were significantly different in milk yield at the first lactation (kg) (P < 0.01), milk fat yield (kg) (P < 0.05) and milk protein yield (kg) (P < 0.01). For the last trait the difference was significant also between cows with genotypes G/G and A/A for rSNP NCE7 (P < 0.05). © 2011 Elsevier B.V.

The Royal Swedish Academy of Sciences has announced the recipients of the 2016 Crafoord Prizes in Mathematics and Astronomy. The Crafoord Prize in Mathematics has been awarded to Yakov Eliashberg of Stanford University “for the development of contact and symplectic topology and groundbreaking discoveries of rigidity and flexibility phenomena.” The 2016 Crafoord Prize in Astronomy has been awarded to Roy Kerr of the University of Canterbury, Christchurch, New Zealand and to Roger Blandford of Stanford University “for fundamental work on rotating black holes and their astrophysical consequences.” The prize money is 6 million Swedish kronor per prize, and the Crafoord Prize in Astronomy is shared equally between the Laureates. The Royal Swedish Academy of Sciences, founded in 1739, is an independent organization whose overall objective is to promote the sciences and to strengthen their influence in society. The Academy states that it “takes special responsibility for the natural sciences and mathematics, but endeavors to promote the exchange of ideas between various disciplines.” The Academy awarded the Crafoord Prize for the first time in 1982 after receiving “a considerable donation” from the Lund industrialist Holger Crafoord and his wife Anna-Greta in 1980. This donation forms the basis of the Anna-Greta and Holger Crafoord Fund, whose aims are “to promote pure research in mathematics and astronomy, biosciences (in the first place ecology), geosciences and polyarthritis (rheumatoid arthritis).” These disciplines are chosen so as to complement those for which the Nobel Prizes are awarded. The prize sum of SEK 6 million makes the Crafoord one of the world´s largest scientific prizes. The international prize is awarded for one field per year in a fixed order to researchers who have made decisive contributions within their fields: Since 2012, there have been two separate prizes in astronomy and mathematics awarded at the same time. The prize in polyarthritis is awarded only when a special committee has shown that scientific progress in this field has been such that an award is justified. The laureates are announced in mid-January each year, and the prize is presented in April/May on “Crafoord Day." It is received from the hand of His Majesty the King of Sweden. In connection with Crafoord Day, a symposium in the discipline in question is arranged by the Royal Swedish Academy of Sciences. The Academy reports that Russian-American mathematician Yakov Eliashberg is one of the leading mathematicians of our time. For more than 30 years, he has helped to shape and research a field of mathematics known as symplectic geometry, and one of its branches in particular — symplectic topology. Eliashberg has solved many of the most important problems in the field and has found new and surprising results. He has further developed the techniques he used in contact geometry, a twin theory to symplectic geometry. While symplectic geometry deals with spaces with two, four or other even dimensions, contact theory describes spaces with odd dimensions. Both theories are closely related to current developments in modern physics, such as string theory and quantum field theory. Symplectic geometry’s link to physics has old roots. For example, it describes the geometry of a space in a mechanical system, the space phase. For a moving object, its trajectory is determined each moment by its position and velocity. Together, they determine a surface element that is the basic structure of symplectic geometry. The geometry describes the directions in which the system can develop; it describes movement. Physics becomes geometry. One of Eliashberg’s first, and perhaps most surprising, results was the discovery that there are regions where symplectic geometry is rigid and other regions where it is completely flexible. But where the boundary is between the flexible and the rigid regions, and how it can be described mathematically, is still a question awaiting an answer. Yakov Eliashberg was born in 1946 in St. Petersburg, Russia. He receiced his Ph.D. at Leningrad State University 1972. Eliashberg is the Herald L. and Caroline L. Ritch Professor of mathematics at Stanford University. The Academy explains in a background piece for this year’s prize that black holes are the source of the universe’s most powerful radiation, as well as of jets that can stretch many thousands of light years out into space. Roger Blandford’s theoretical work deals with the violent processes behind these phenomena. Roy Kerr laid the foundation for this research early on, when he discovered a mathematical description of rotating black holes. This became one of the most important theoretical discoveries in modern cosmology. The prediction of black holes is one of the perhaps strangest results of the general theory of relativity. When Albert Einstein finally presented his theory, in November 1915, he described gravity as a geometric property of space and time, spacetime. All objects with mass bend spacetime; they create a pit into which smaller objects can fall. The greater the mass, the deeper the pit. The mass of a black hole is so great that nothing that ends up in there can escape, not even light. It was not until 1963 that mathematician Roy Kerr succeeded in solving Einstein’s equations for rotating black holes. That the holes should rotate is feasible because the stars from which they originated should have rotated. At about the same time, astronomers discovered galaxies that emitted light and other electromagnetic radiation that was so strong it outshone several hundred ordinary galaxies. They were named quasars. Nothing other than a black hole could give the quasars their luminosity. So how is the strong light of rotating black holes created? This question was answered by Roger Blandford and his colleagues in the 1970s. Ever since, he has refined and made more realistic models of how gas surrounding a black hole flows towards it, is heated up and transforms some of its gravitational energy to radiation. While this is happening, electrically charged particles are sent millions of kilometers into space in the form of powerful jets. The source of all of this power is the rotational energy of the massive black hole. Roy Kerr was born in 1934 in Gore, New Zeeland. He received his Ph.D. in 1959 at the University of Cambridge. Kerr is an Emeritus Professor at the University of Canterbury, New Zeeland. Roger Blandford was born in 1949 in Grantham, Great Britain. He received his Ph.D. in 1974 at the University of Cambridge. Blandford is Luke Blossom Professor in the School of Humanities and Sciences,  at Stanford University.

Two displays of the humanitarian trend in Russian geography are considered. The first one connects the strengthening of attention to a man as a member of social and geographic community to his spatial activity and perception of geographic reality (humanization); the second reflects the application of sources and methods of sociology, ethnography, history, ethno linguistics and other branches of science (humanitarization). It's noted the integrative tendencies in modern science promote complex research of geographic reality (objective, social and individual) and its reflections in geographic conceptions and images. The main problem of humanitarian geography is also formulated.

Activity theory (AT) is the most recognised part of Russian psychology outside Russia. However the general view of AT in international science is rather unilateral, lacking substantial aspects and areas necessary for proper understanding. This article is aimed at expanding the image of AT dominant in the mainstream which reduces the AT trend to A.N. Leontievs theory. This reduction impoverishes the creative potentialities of the trend, and decreases the ability of AT to contribute to international science. We aim to reveal that AT is not limited to Leontievs approach, to explain which ideas of the founders of AT, S.L. Rubinstein and L.S. Vygotsky, were pursued and which were rejected by A.N. Leontiev, and to assess another important contribution to the AT trend - the theory of B.G. Ananiev, where the ideas of ATs founders were developed which were not succeeded by A.N. Leontiev. Historical causes and consequences of the general reduction of the image of AT in the mainstream to Leontievs theory are considered: why the discrepancies between views of Rubinstein, Vygotsky and Leontiev were hardly ever discussed in public and why other theories contemporary to Leontievs theory were never given account appropriate to their value in Russia and remain almost unknown abroad.

Development of the traditional economy of indigenous small-numbered Northern peoples acts as the production basis for retaining the most important features of their ethnic identity. Today, the main sector of traditional activity is reindeer breeding, which in contrast to other sectors is mainly based on production technology and organization that arose many centuries ago. Such a system of operating an economy, preserving a unique culture, language, and traditions, results in a nomadic way of life for the reindeer-breeding population and low efficiency of production and income level of workers. However, at present, it has virtually no alternative. In the situation that has evolved, state financial support of the sector acts as an important element of economic and ethnic policy. In substantiating the retention of this policy and directions of its implementation, the paper analyzes the natural and economic conditions of the sector development and makes corresponding conclusions and recommendations.

Mutations in sup1 and sup2 genes may cause cycloheximide-dependent growth in yeast Saccharomyces cerevisiae. Two classes of such mutants are described in the paper: 1) high temperature sensitive mutants, which do not express their sensitivity to nonpermissive temperature in the presence of cycloheximide (conditionally dependent) and 2) mutants unable to grow in the absence of the drug (true dependent). Some of the mutants of both classes express dependence toward another antibiotic - trichodermine. The binding of H(3)-labelled cycloheximide studied by equilibrium dialysis has demonstrated that both 80S ribosomes and 60S subunits isolated from conditionally dependent mutant showed a higher affinity for the drug compared to that of a parent strain. The number of binding sites per ribosome or per 60S subunit in the cycloheximide dependent mutant remains unchanged.Circular dichroism spectra of a mutant ribosomes in the presence as well as in the absence of antibiotic revealed that sup1 and sup2 mutations alter conformation of the yeast cytoplasmic ribosomes. The binding of cycloheximide to mutant ribosomes induces a conformational shift, which presumably compensates for their functional defect.

We have made a large scale analysis of prototrophic products of spontaneous and induced mitotic recombination within LYS2 gene of the yeast Saccharomyces. The mutant alleles staying in heterozygote with the wild type allele were uncovered and analysed.Among thirteen lys2 mutations used in the study three had reduced frequencies of mitotic gene conversion. These rarely converting mutations gave a remarkably high proportion of reciprocal events (up to 38%) in pairwise combinations, never seen for any other pair of alleles studied. Two of these mutations are the deletions of large parts of LYS2 gene.The results suggest that mispairing in the region of deletion blocks the hybrid DNA migration and leads to the reduced conversion ability of deletions. Comparison of uncovered alleles ratio in all allele combinations tested lead us to another hypothesis about bidirectional migration of hybrid DNA.

Spheroplast fusion induced by polyethylene glycol often occurs during transformation of yeast spheroplasts. It leads to the appearance of polyploid transformants. We have developed a method of discriminating between haploid and polyploid transformants, based on qualitative comparison of the frequency of mitotic homozygotization for a recessive marker, lys2, in diploid and polyploid hybrids of transformants crossed with a tester haploid bearing lys2.We have used this method to compare the frequency of appearance of polyploids during transformations of spheroplasts and of intact cells using lithium chloride in the strain DC5. Polyploids constitute from 15% to 74% of transformants after transformation of spheroplasts. In lithium chloride transformation polyploids arose in only one of four experiments and constituted 9% of transformants.
